- REFBIGERATING APPARATUS.

Specification of Letters Patent.

Patented July 2.0, 1909.

Application filed November 16, 1908. Serial No. 462,766.

To all whom it may concern:

Be it known that I, Josnrn SomzEIBLn, a

the gas to the compressor and the liquid to the refrigerating 0011.

The primary object of my inventionjis to produce such effective separation of the gas from the liquid as will insure the return of the as in a dry state to the compressor or a sorber; and this and other objects are accomplished by the construction illustrated in the accompanying drawing, in which Figure 1 is a broken view showing a duplicate set, for the purpose hereinafter explained, of my improved apparatus in elevation, and Fig. 2' is a plan section through' the separator, showing a modification by dotted representation.

The separator 3 is preferabl constructed of metal in the general conoi a1 shape represented and i equipped with a pressurega e 4. A dis' barge-pipe 5 carrying aliqui age 6 leads from the lower narrow end of t e separator to a refrigerator coil or chamber (not shown) of the system, and a gas-discharge pi .e 7, containing a valve 8 or controlling t e pressure in the separator against disturbance in the system, leads centrally from the top of the latter to the compressor or absorber (not shown) of the refrigerating system. Aheader 9, to which one or more pipes 10 lead fromthe dischargeendof the said coil orchamber, has ,a p1pe connection 11 with a nipple 12 leadingtangentially into the to -portion of the separator for discharging therein the refrigerant in liquid and vapor form from the coil or chamber, and into this nipple leads a valved branch 13 of a supply-pipe 14, extending from a suitable source (not shown) for the refrigerant in 1i uid form, for replenishing contemplates the use of any liquefia separator; the end of the branch inthe ni ple being deflected, as shown, for .propery' directing the discharge therein.

The remainder of the apparatus illustrated in Fig. 1 isa substantial duplicate of the details of that described, for the purpose hereinafter explained, and involves a separator 33 equipped with a pressure-gage 44, a pipe carrying a liquid-gage 66, a gas-discharge pipe 77 containing a pressure regulating valve 88 and to which the pipe 7 is shown to be coupled, a nipple 112 leading tangentially into the larger end of the separator and a pipe 1 10 connecting therewith the dischargeend of the coil or chamber, with the valved.

pipe 14'projeeting into the nipple past the point of dischargeinto it of the p1 e1 10.

, In instances it maybe desirabe to du licate the ni ple 12 (and 112), as indicate in" Fig. 2, an cause the two to communicate tangentially with the u separator at diametrica y thereof.

For the purpose of the following description of the operation, which need, in t 'e main, relate only to the first described apparatus, anhydrous ammonia ma be reopposite points er portion of the arded as the refrigerant employe though 1t is to be understood that m invention le gas.

The tangential discharge 1nto the upper part of the separator of the liquid refr gerant and vaporized portion carried by 1t ls'so 0t er suitable forcible as to course it centrifug'ally about the inner surface of the separator-wall, leaving the interior of the separator, meaning the space therein bounded y thecentnfugall coursing refrigerant, open. The force of t e centrifugal action separates Into this space,

'fromthe flowing liquid and vapor, the gas in adry condition, in which 1t flows throu h the space to the compressor through t e z 'lhe gist of m lnventlon hes III the cen trifugal action 0 the refrigerant in the sepa rator 'whereby the liberation 1s v effected of the gas in a dry state, andthis whatever means be employed for producing that aetion; so that -my mventionis not intended to be limited to the particular means for the purpose shown and described.

v To maintain the desired flooded condition ,of the refrigerator coil or chamber, the su ply of liquid ammonia in thesystem may e replenished in the separator from vtime to time, under guidance of the gage 6, on opening the valve iii the pipe 13. Moreover, ari important advantage ensues from introducing this replenishing supply by way of the nipple, since it instantaneously assumes the temperature of the refrigerant in the latter and enhances recipitation of the heavier vapor against tlie separator-wall.

The valve 8 in the gas-return pipe 7 serves to regulate the ressure in the system according to the other matter to be refrigerated requ res to be cooled, such as wort requiring to be cooled toabout 40 F. and fermented beer to about 30 F. and thus enables the boiling (evaporating) point of the liquid refrigeiant to be controlled in accordance with the degree of refrigeration sought. This provision permits the use of one suctionpressure in a refrigerating system involving a plurality of my improved apparatus for simultaneously cooling liquids or ot er material requiring) to be cooled to different temperatures, y maintaining'the suctionpressure adapted for the lowest temperature of refrigeration. Thus, in the illustrated, apparatus, the regulating valve 8 may be set for maintaining a maximum pressure in the separator 3 for allowing the temperature in a coil connected with the pi e 5, for cooling to F. fermented beer, w ile the valve 88 may be set for maintaining a lower pressure in the separator 33 for attaining the temperature in a coil connected with the 3-5 pipe 55 for cooling wort, while the suctionpressure in the pipe 7 Z is that for the lowest of these. two temperatures.
